Action Replay AMX

Action Replay A.M.X.

Made by Datel Electronics.

Now, thanks to Jose Leandro, the hardware specialist of the spectrum, with his famous page :

We can know more about this hardware.

The hardware only has RAM and not ROM, therefore the device needs software programmed into the RAM to use it.

Technical

• Has a write only I/O port &FBFB/&FAFB (partially decoded. A10=0, A2=0). A8 controls ROMDIS/RAMDIS signal. Cleared by RESET.
• Freeze button seems to trigger normal interrupt (not NMI?)
• Seems like there is rom and ram access.
• The unit has a switch for load/save, looks like A12 is driven depending on that.
